 Volume (V)
 Temperature (T)
 Amount in Moles (n)



Term
What do the gas laws describe? 

Definition
The relationships between pairs of the properties of gases. 


Term
What is the relationship between volume and pressure? 

Definition
There is an inverse relationship  an increase in one results in a decrease in the other. 


Term
What does Boyle's Law assume? 

Definition
Constant temperature and constant amount of gas. 


Term

Definition
At a constant temperature, the volume occupied by a fixed amount of gas is inversely proportional to the applied pressure.
P_{1}V_{1}=P_{2}V_{2} 


Term

Definition
At constant pressure, the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature. 


Term
How are volume and temperature related? 

Definition
Volume and temperature are linearly related. 


Term
If two variables are linearly related, what does that mean? 

Definition
Plotting one against the other on a graph produces a straight line. 


Term
What does extrapolate mean? 

Definition
To extend a graph past its plotted points. 


Term
What is the value of absolute zero? 

Definition


Term
What is the combined gas law? 

Definition
A combination of Charles's Law and Boyle's Law. 


Term

Definition
At fixed temperature and pressure, the volume of gas is directly proportional to the amount of any gas. 


Term
What does GuyLussac's Law assume? 

Definition
Constant volume and number of moles.
